POWER-CONVERTER FOR CONVERTING RECIPROCATING INTO ROTARY MOTIO N.

SPECIFICATION forming part of Letters Patent No. 253,515, dated February14, 1882.

Application filed December 27, 1881. (No model.)

To all whom it may concern Be it known that I, HENRY GROFT, Jr.,residingat Springfield, Clarke county, Ohio, have invented certain newand usefulImprovements in Power-Converters for Converting Reciproeatinginto Rotary Motion, and it is designed especially for a power-converterfor wind-engines, of which the followingis a specification.

In this class of machines there is usually a vertically-reciprocatin gpump-rod operated by a crank or eccentric on the wind-wheel shaft,

and it has long been a problem to utilize the power of the wind-wheelfor grist-mills, cornshellers, and the like machinery. I am aware thatmachinery for this purpose has been designed before, butfor variousreasons has failed in producing satisfactory results with smallwind-wheels or those of comparatively limited power.

My present invention has for its object the utilization of the largestper cent. of the power of the wind-wheel for the purpose of runningmachines of the class above designated, orgenerally any machinery withinthe power of the wheel.

The novelty of my invention consists in the combination, with thereciprocating pump-rod and the driving-wheel of the motor-engine, whoseshaft is provided with ratchets, of alternately-aetin g dogs operatedfrom the pump-rod through the medium of links and levers,whereby acontinuously-revolving motion is imparted to the driving-wheel; also, indetails of construction and combinations ofthe parts, as will beherewith set forth.

In the accompanying drawings, Figure 1 is a side elevation of myapparatus. Fig. 2 is an end view of the same. Fig. 3 is an enlargeddetail view of the ratchet and dog-carrying link with one side brokenaway. Fig. 4 is a plan view of the ratchet, dog, and link.

The same letters refer to like parts in the difl'erent figures.

A, Fig. 2, is the lower end of the pump-rod,

which works up and down in the usual way. It is pivoted by means of thelink a to thevibrating cross-beam 13, which is pivoted at its center 12toany suitable frame-work. The two beams G G are pivoted by means oflinks a to the ends of the vibrating beam B in any suitable manner. Uponthe lower beams, O (J, are secured metal links d, in the lower end ofwhich are pivoted the slotted blocks D.

In any properly-constructed framework, E, is journaled a shaft, F,carrying a drivingwheel, G. Upon the outer ends of shaft F are keyed orotherwise fastened ratchet-wheels H. Straddling each of these ratchetsand hung upon the shaft F are links I, with rearward extensions whichpass through the slot in the links d, and are held adjustably byset-screws f, inserted through the tops of the links d.

Pivoted in or near the forks of the links I,

are dogs J which engage with the ratchets, as shown, and may be held toplace by gravity or by any suitable superimposed springs.

I By the above construction it will be readily understood that as thepump-rod A moves up and down the beam B is vibrated upon 'its pivot, andan alternating reciprocating motion is given to the beams G and 0. Thesein turn vibrate the dog-carrying links with alternate motions, so thatwhile the one by means of its dog is rotating its ratchet,and with itthe driving-wheel, the other is being depressed, carry-, ing its dogback for a fresh engagement with its ratchet, and vice versa. Thus aconstant revolution is imparted to the driving-wheel G in one continuousdirection.

By means of the adjustability of the links I in the slotted blocks Deitherdog may be given a greater or less amount of play, and so eitherthe up or the down stroke of the pumprod may be favored, as desired.This same object may be accomplished by rendering the pumprod or thebeams O O laterally adjustable.

I prefer that the driving-wheel should have sprockets upon itsperiphery, so that a chain may be used for communicating motion to thedriven machinery, instead of belts, though the latter may be used, ifdesired.

- I do not wish to limit myself to the precise constructionandarrangement shown, as this may be varied without departing t'rommyinvention. For instance, the pump-rod, instead of being coupled to thebeam B at a point between its pivot and that of one of the beams G or 0,may be coupled to an extension of the beam beyond either of the beams,so as'to obtain a longer leverage and greater power, though at asacrifice of the length of stroke of the dogs; also, instead ofratchet-Wheels and dogs, spring-clutches might be employed,'or.

5 the Wheels H might have smooth peripheries and friction gripes orrollers be used.-

Having thus fully described my invention, I claim- 1. In apower-converter, the combination, 10 with a driving-wheel whose shaft isprovided with ratehets arranged on each side of the driving-wheel, of avibrating pivoted beam actuated by the reciprocating rod and carrying atits ends beams provided at theirlower ends I 5 with dogs and connectingmechanism, substantially as described, whereby the vibration of
